Description

The present invention relates to a practice system, practice method, and program for practicing musical ensemble playing online, as well as an instructor terminal device.

There is a known technology that provides appropriate training tailored to the characteristics of a player when learning how to play an instrument (for example, the technology described in Patent Document 1). This conventional technology makes it possible to adjust the practice piece to a piece that matches the player's technical level based on pre-stored profile information that indicates the player's playing characteristics, etc.

JP 2002-202776 A

However, while the above-mentioned conventional technology describes adjusting practice pieces to match the technical level of each individual performer, it has the problem of not being able to handle situations such as sessions where multiple students practice one piece together. In particular, when students take online lessons, which has become increasingly common in recent years, network delays and other factors make it difficult to hold joint lessons between multiple students at a technical level appropriate for the students.

Therefore, the present invention aims to enable practice that is appropriate for each of multiple students.

An example of a practice system is a practice system that includes a performer terminal and an instructor terminal. The performer terminal includes a first communication unit that communicates with at least the instructor terminal, and a performance level acquisition unit that acquires the performance level of the performer corresponding to the performer terminal and transmits it to the instructor terminal via the first communication unit. The instructor terminal includes a second communication unit that communicates with at least the performer terminal, and a part assignment determination unit that receives the performance levels of the multiple performers transmitted from the performance level acquisition units of the multiple performer terminals via the second communication unit and determines the part that each of the multiple performers will be responsible for playing.

The present invention makes it possible to provide practice that is appropriate for each of multiple students.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
1 is a block diagram showing an example of the system configuration of an embodiment of a practice system 100 according to the present invention that allows online musical ensemble practice. The practice system 100 has a system configuration in which student personal computers (hereinafter referred to as "student PCs") 101, each connected to electronic musical instruments 103 (e.g., #1 to #6), and a teacher personal computer (hereinafter referred to as "teacher PC") 102, which is an instructor's terminal, are mutually connected via a network 104 such as the Internet or a local area network.

Figures 2(a) and (b) are block diagrams showing examples of the hardware configurations of the student PC 101 and the teacher PC 102 in Figure 1, respectively.

First, the student PC 101 in FIG. 2( a) has a hardware configuration in which a CPU (Central Processing Unit) 201, a ROM (Read Only Memory) 202, a RAM (Random Access Memory) 203, an external storage device 204, an input unit 205, a display/output unit 206, a communication unit 207, a MIDI (Musical Instrument Digital Interface) communication unit 208, and a camera unit 209 are interconnected by a system bus 210.
The student's PC 101, which is the performer's terminal, is preferably a personal computer, but may also be a smartphone terminal device or a tablet terminal device.

In the student PC 101 of FIG. 2(a), the CPU 201 reads out a control processing program stored in the ROM 202 into the RAM 203 and executes it, thereby executing the processing functions of steps S401, S402, and S405 to S410 in the flowchart illustrated in FIG. 4 described later.
In these processes, the CPU 201 of the student PC 101 executes a performance level acquisition process to acquire the performance level when a player corresponding to the student PC 101 plays an electronic musical instrument 103 (see Figure 1) connected to the student PC 101.
In addition, the CPU 201 of the student PC 101 executes a performance level transmission process to transmit the information on the performance level acquired in the performance level acquisition process to the teacher PC 102 via the communication unit 207, which is the first communication unit.

In the student PC 101 in FIG. 2(a), the external storage device 204 is, for example, an SSD (solid state disk). The external storage device 204 stores score information for the practice piece, automatic accompaniment data or model performance data for the piece, and information sent from the teacher PC 102 indicating the part to be played by the performer corresponding to the student PC 101.

In the student PC 101 in FIG. 2(a), the input unit 205 and display/output unit 206 are, for example, a keyboard and mouse input device and a liquid crystal display device, or a touch panel input/display device. This input unit 205 allows the performer to input various instructions and to instruct the start of automatic accompaniment or model performance. In addition, the display/output unit 206 displays the sheet music of the practice piece and the part that the performer corresponding to the student PC 101 is responsible for.

In the student PC 101 in FIG. 2(a), the communication unit 207 functions as a first communication unit, and communicates with the communication unit 207 in the teacher PC 102 (see FIG. 2(b)) via the network 104 in FIG. 1.

In the student PC 101 in FIG. 2(a), the MIDI communication unit 208 is connected by wire or wirelessly to the MIDI communication unit 310 (see FIG. 3 described later) built into the electronic musical instrument 103, and receives MIDI data, which is performer performance data output from the electronic musical instrument 103 (see FIG. 1 and FIG. 3) to which the student PC 101 is connected, based on the performance of the performer on that electronic musical instrument 103.

In the student PC 101 in FIG. 2(a), the camera unit 209 captures a performer's performance video showing the performer playing the electronic musical instrument 103 to which the student PC 101 is connected.

Next, the teacher's PC 102 in Figure 2(b) has a hardware configuration similar to the student's PC 101 in Figure 2(a), in which a CPU 201, a ROM 202, a RAM 203, an external storage device 204, an input unit 205, a display/output unit 206, and a communication unit 207 are interconnected by a system bus 210.
However, the teacher's PC 102 does not include the MIDI communication unit 208 and the camera unit 209 that are included in the student's PC 101 in FIG.
The teacher's PC 102, which is the instructor's terminal, is preferably a personal computer, but may also be a tablet terminal device or the like.

In the teacher's PC 102 of FIG. 2(b), a CPU 201 reads a control processing program stored in a ROM 202 into a RAM 203 and executes it, thereby executing the processing functions of steps S403, S411, and S412 in the flowchart illustrated in FIG. 4, which will be described later.
In these processes, the CPU 201 of the teacher PC 102 executes a part determination process which determines the part that each of the performers will be responsible for, depending on the performance levels of the multiple performers, which are transmitted via the communication unit 207 of each student PC 101 (see Figure 2(a)) and received from the multiple student PCs 101 by the communication unit 207 of the teacher PC 102 (see Figure 2(b)).
In addition, the CPU 201 of the teacher's PC 102 executes a part assignment sending process to send information indicating the parts that each of the multiple performers will be responsible for playing via the communication unit 207 (see Figure 2 (b)) to the student's PCs 101 corresponding to the multiple performers.

In the teacher's PC 102 in FIG. 2(b), the external storage device 204 is, for example, a hard disk drive or an SSD similar to that in the student's PC 101 in FIG. 2(a). The external storage device 204 stores MIDI data and performer performance video data, which are performance data sent from one or more student PCs 101, as well as MIDI data and performer performance video data of an entire piece of music assembled based on these.

In the teacher's PC 102 in FIG. 2(b), the input unit 205 and display/output unit 206 are, for example, a keyboard and mouse input device and a liquid crystal display device and a sound system, or a touch panel input/display device and a sound system. The teacher uses this input unit 205 to input various instructions. The display/output unit 206 also displays a video of one or more performers' performances, which shows the final performance of the one or more performers, and plays the sound of the final ensemble performance of the one or more performers.

In the teacher's PC 102 in FIG. 2(b), the communication unit 207 functions as a second communication unit, and communicates with the communication unit 207 (see FIG. 2(a)) in each student's PC 101 via the network 104 in FIG. 1.

Figure 3 is a block diagram showing an example configuration of an electronic musical instrument 103 connected to each student's PC 101 of the practice system 100 in Figure 1. This electronic musical instrument 103 is, for example, an electronic piano. The electronic musical instrument 103 has a hardware configuration in which a CPU 301, a ROM 302, a RAM 303, a keyboard section 304, an operation section 305, a sound source section 307 in a sound system 306, and a MIDI communication section 310 are interconnected by a system bus 311.

The CPU 301 reads out the control processing program stored in the ROM 302 into the RAM 203 and executes it to control the entire system, detect the performance operations of pressing/releasing each key on the keyboard section 304 and instruct the sound source section 307 to sound/mute accordingly, detect the operation of various switches on the operation section 305 and perform control processes accordingly, read out automatic accompaniment data or model performance data from the ROM 302 or RAM 303 and instruct the sound source section 307 to play automatic accompaniment or model performance accordingly, and so on.

The ROM 302 stores the control processing programs described above, as well as waveform data for generating musical tones of various tones, automatic accompaniment data, model performance data, etc.

RAM 303 temporarily stores the aforementioned control processing program and various variable data used during its execution, waveform data corresponding to the practice piece, automatic accompaniment data, model performance data, etc.

The sound system 306 includes a sound source unit 307, an audio circuit 308, and a speaker 309. The sound source unit 307 generates musical tone signal data based on the waveform data that the CPU 301 reads out from the ROM 302 and sets, and on/off instructions specified by the CPU 301. The musical tone signal data generated by the sound source unit 307 is D/A converted to an analog musical tone signal in the audio circuit 308, amplified, and output from the speaker 309.

The operation unit 305 includes at least a performance start/stop switch that instructs the start/stop of a performance, in addition to a general tone color selection switch.

When the performance start/stop switch is pressed, the CPU 301 begins reading out the automatic accompaniment data or model performance data of the specified piece of music from the ROM 302, and instructs the sound source section 307 to produce predetermined accompaniment sounds or model performance sounds in accordance with the automatic accompaniment data or model performance data.
As a result, the automatic accompaniment sounds or model performance sounds are output from the sound source section 307 via the audio circuit 308 and the speaker 309 .

The CPU 301 instructs the sound source unit 307 to generate/mute sounds corresponding to the key press/release operations performed by the performer on the keyboard unit 304 in time with the above-mentioned automatic accompaniment sounds or model performance sounds emitted from the speaker 309.
As a result, the performance sound produced by the performer is output from the sound source section 307 via the audio circuit 308 to the speaker 309 .

In conjunction with the above-mentioned sound emission operation, the CPU 301 creates MIDI data corresponding to the sound generation/silence instructions based on the performer's performance that are instructed to the sound source unit 307, and transmits the created MIDI data from the MIDI communication unit 310 in FIG. 3 to the MIDI communication unit 208 in the student PC 101 in FIG. 2(a).

Figure 4 is a flow chart showing an example of the control process of the practice system 100 described in Figures 1 to 3. This control process consists of control processes in the student PC 101 (steps S401, S402, and S405 to S410) and control processes in the teacher PC 102 (steps S403, S404, S411, and S412). The control process in the student PC 101 is a process in which the CPU 201 reads out a control process program stored in the ROM 202 into the RAM 203 and executes it in the student PC 101 of Figure 2 (a). The control process in the teacher PC 102 is a process in which the CPU 201 reads out a control process program stored in the ROM 202 into the RAM 203 and executes it in the teacher PC 102 of Figure 2 (b), similar to the case of the student PC 101.

First, each student inputs his/her name, ID, etc., from the input unit 205 (see FIG. 2(a)) of his/her student PC 101 (step S401 in FIG. 4). Alternatively, the student may input his/her name in advance from the input unit 205 into the student PC 101, and when practice begins, his/her name that has been registered in advance may be automatically specified.

Next, the CPU 201 of the student PC 101 executes a performance level acquisition process corresponding to the performance level acquisition unit (step S402 in FIG. 4). In this process, the CPU 201 of the student PC 101 acquires the student's performance level and transmits it to the teacher PC 102 via the communication unit 207.

FIG. 5A is an operational explanatory diagram for explaining a first technique for acquiring a performance level in the performance level acquisition process in step S402.
First, via the display/output unit 206 of the student PC 101 or using paper media, a student corresponding to the student PC 101 is presented with, for example, three questionnaire documents such as "I can play simple songs with one hand,""I can play with both hands," and "I am confident that I can play even difficult songs if I practice," as exemplified in the leftmost items in Figure 5 (a).
The student answers each of the three documents in the questionnaire by tapping, for example, either "YES" or "NO" on the input unit 205 of the student PC 101, such as a touch panel.
The CPU 201 of the student PC 101 determines which playing level the student has, out of "beginner,""elementary,""intermediate," or "advanced," based on the student's responses to the questionnaire and a judgment table, for example, of FIG. 5(a) stored in the ROM 202.

FIG. 5B is an operational explanatory diagram for explaining a second technique for acquiring a performance level in the performance level acquisition process in step S402.
The CPU 201 of the student PC 101 selects from the music score data stored in the ROM 202, starting with the easiest scores, and displays the music score, for example as shown in Figure 5 (b), and a selection answer screen asking whether the student can play the music score on the display/output unit 206, for example a touch panel of the student PC 101.
The student uses an electronic musical instrument 103 connected to the student PC 101 to play the musical score displayed as shown in FIG. 5(b), judges whether or not he or she can play it, and answers by tapping on the touch panel either "I can play it" or "I can't play it."
The CPU 201 of the student PC 101 sequentially selects sheet music data of increasing difficulty from the ROM 202 and displays the same as in Figure 5 (b) on, for example, a touch panel of the student PC 101, and the student responds to the display with "I can play it" or "I can't play it."
Based on the answer and a judgment table stored in ROM 202, such as that shown in FIG. 5(c), the student's PC 101 judges the student's playing level among "beginner,""elementary,""intermediate," or "advanced."

Returning to the explanation of FIG. 4, the CPU 201 of the teacher's PC 102 in FIG. 2(b) receives the performance levels of each of the students #1 to #6 acquired and transmitted in step S402 in FIG. 4 from, for example, six student's PCs 101 #1 to #6 in FIG. 1 via the communication unit 207 (see FIG. 2(b)).
As a result, the CPU 201 of the teacher's PC 102 compiles the distribution of the performance levels of each of the students, for example, #1 to #6, as shown in FIG. 5(d).
Then, the CPU 201 of the teacher's PC 102 displays the recommended practice scores stored in the ROM 202 in advance on the display of the display/output unit 206, corresponding to the performance level with the highest distribution rate in the collected results (step S403 in FIG. 4). In the example of FIG. 5(d), since there are many beginners, scores for beginners are presented. In this case, one or more scores may be presented.

The teacher selects one of the recommended practice scores displayed on the display in step S403, and executes a part determination process for the selected score corresponding to the part determination section (step S404 in FIG. 4).
Specifically, the CPU 201 of the teacher PC 102 determines, for each of the students #1 to #6, a part with a bar length corresponding to the performance level notified from each of the student PCs 101 #1 to #6 in the score selected based on the recommended practice score displayed on the display in step S403, while referring to a standard in a table of the part length (division length) for each performance level determined in advance. The CPU 201 of the teacher PC 102 may also randomly select one of the recommended practice scores displayed on the display.
FIG. 6 is a diagram showing an example of parts on a score assigned to each student when there are six students for a certain practice score. Since Mr. F has an advanced level of performance, many consecutive bars or bars with a relatively high level of difficulty are determined as his part. Since Mr. C has an intermediate level of performance, the number of bars is large, but bars that are easier than Mr. F's part are determined as his part. Similarly, since Mr. E has an intermediate level of performance, bars with a medium level of difficulty are determined as his part. Since Mr. A, Mr. B, and Mr. D have beginner levels of performance, short bars or bars with a relatively low level of difficulty are determined as his part. In the example of FIG. 6, it is assumed that there are no students at the beginner level.
The CPU 201 of the teacher PC 102 transmits the part (including the bar number and music information) assigned to each student, determined as described above, from the communication unit 207 (see Figure 2 (b)) of the teacher PC 102 to each of the student PCs 101, #1 to #6.

In each of student PCs 101 #1 to #6, the CPU 201 of the student PC 101 receives the assigned part designated by the assigned part determination process in step S404 of FIG. 4 via the communication unit 207 (see FIG. 2(a)). As a result, the CPU 201 of the student PC 101 reads the score data of the piece corresponding to the designated assigned part from the ROM 202, and displays the part to be played by the performer corresponding to this student PC 101 on the display/output unit 206 of this student PC 101, for example a touch panel (step S405 of FIG. 4).

Next, the CPU 201 of the student PC 101 sets a tempo in the electronic musical instrument 103 connected to the student PC 101 according to the performance level acquired in the performance level acquisition process of step S402 via the MIDI communication unit 208 (see FIG. 2(a)) and the MIDI communication unit 310 (see FIG. 3) in the electronic musical instrument 103 (step S406 in FIG. 4), and starts automatic accompaniment or model performance from the designated performance part at the set tempo (step S407 in FIG. 4). Setting a tempo according to the performance level means, for example, having an advanced player play at a default tempo, and setting the tempo to be slower as the performance level decreases to that of a beginner.
In this case, the student's PC 101 can cause the electronic musical instrument 103 to start automatic accompaniment or model performance, for example, one bar before the performance point of the part that the student is responsible for.

After the automatic accompaniment or model performance of the assigned part on the electronic musical instrument 103 has begun in step S407, the performer plays the assigned part on the keyboard section 304 (see FIG. 3) of the electronic musical instrument 103, and the performance sound is emitted from the sound system 306.
At the same time, the CPU 301 of the electronic musical instrument 103 sequentially outputs MIDI data corresponding to the sounds played by the performer from the MIDI communication section 310 in FIG. 3 to the MIDI communication section 208 in the student PC 101 in FIG. 2(a).
The CPU 201 of the student PC 101 temporarily stores the MIDI data for the parts played by the above-mentioned performers received via the MIDI communication unit 208 in the RAM 203 or the external storage device 204 as performer performance data (step S408 in Figure 4).

In addition, at the same time as the automatic accompaniment or model performance of the assigned part on the electronic musical instrument 103 begins in step S407, the CPU 201 of the student PC 101 captures, with the camera unit 209, a video of the performer's performance showing the performer playing the electronic musical instrument 103 connected to the student PC 101.
Then, the CPU 201 of the student PC 101 temporarily stores the performer performance video of the performer playing the part that he/she is responsible for in the RAM 203 or the external storage device 204 as performer performance video data (step S409 in FIG. 4).

After a performer has played their assigned part several times, when they decide that they are ready to end the practice, they tap the end practice button on the touch panel of the student PC 101. As a result, the CPU 201 of the student PC 101 transmits the MIDI data and performer performance video data of the performer's performance data for their assigned part, which were temporarily stored in the RAM 203 or external storage device 204, to the teacher PC 102 via the communication unit 207 (see FIG. 2(a)) (step S410 in FIG. 4). This step S410 corresponds to the processing functions of the performer performance data transmission unit and the performer performance video data transmission unit.

When the CPU 201 of the teacher's PC 102 receives the above-mentioned performer performance data and performer performance video data from one of the student's PCs 101 via the communication unit 207 (see FIG. 2(b)), it displays on the display of the display/output unit 206 that the data has been submitted for that student's PC 101 (step S411 in FIG. 4).

For example, when data reception in step S411 from all student PCs 101 #1 to #6 in FIG. 1 is completed, the CPU 201 of the teacher PC 102 assembles (integrates) performance data for the entire song based on the MIDI data, which is the performer performance data of all performers from all student PCs 101 corresponding to all performers, and the parts assigned to all performers determined in step S404 in FIG. 4.
The CPU 201 of the teacher's PC 102 also assembles performance video data for the entire piece based on the performer performance video data of all performers from all student's PCs 101 corresponding to all performers and the parts assigned to all performers determined in step S404 of Fig. 4 (step S412 in Fig. 4). This step S412 corresponds to the processing functions of the performance data assembly unit and the performance video assembly unit. Since the performance data and performance video data are often set to different tempos for each performer, the speed of the performance and video may be changed when assembling each piece of data or when playing back each piece of data to unify the tempo of the entire piece.
The CPU 201 of the teacher's PC 102 transmits the performance data and performance video data of the entire piece created in step S412 to the student's PC 101 and displays them, thereby realizing online ensemble performance even among students with different performance levels.

In the embodiment described above, if a student does not play his/her assigned part well, a practice method can be introduced in which the teacher watches a video of the performer's performance video data and gives advice. In this case, the model performance can be played at a low volume in the video.

In the above-described embodiment, if the performance levels are divided into a mixture of beginners and advanced players, problems may arise such as the advanced players only playing the good parts or the beginners being overwhelmed by the performance of the advanced players.
For this reason, student levels (classes) may be divided into three levels, for example, beginner, intermediate, and advanced, and within those levels students may be further divided into beginners, intermediate, and advanced students according to their relatively similar level.
Then, as described in the embodiment (see step S403 in FIG. 4), the music may be determined according to, for example, the average level of the students.
Also, the parts to be played may be determined by dividing each piece into phrases for beginners, beginner phrases, intermediate phrases, and advanced phrases that are predefined for each piece of music. In other words, measures for beginners, beginners, intermediate phrases, and advanced phrases may be predefined, and the parts to be played by the performers may be allocated based on the results of a questionnaire.

When each student is practicing, for example, the student can press the recording start switch to play a demonstration performance at a low volume as a guide, making it possible to even out the timing of the performance and align the tempo.

As described above, according to this embodiment, the following effects are obtained.
First, it makes it possible to efficiently provide tasks to students at various levels.
In addition, video data of your performance is created, making it easy to check the results of your practice.
In addition, in online (remote) lessons, the situation is generally one teacher to one student, which can often lead to a feeling of loneliness during practice, but in this embodiment, it feels like all the students are playing the practice piece together, which creates a sense of unity.
Even students who are not yet at the level where they can play an entire song can easily participate in practice.
For example, online classes at elementary and junior high schools, beginners, and adults who have started playing again after a long time can easily participate.
